Trivia
When keeping the Y and P keys pressed during boot, you will get a scrolling list of the development team followed by a digitized voice saying "It's a Sony!". A video of it is available here. The Y and P keys seem to refer to "Yellow Panther", which is also encoded as a message at the beginning of the ROM. The message (written backwards in the ROM) reads "A Yellow Panther Production, 1986".
